Chart star Rita Ora dazzled a crowd of tens of thousands in a sequinned mesh dress as she performed at Wembley Stadium.

The singer shared a bill with her ex-fiance, DJ and producer Calvin Harris, at the annual Capital FM Summertime Ball.

Rita rose from a stage in the centre of the London stadium shrouded in a red hooded cape before casting it aside to reveal her skimpy minidress.

Her two-song set included hit single How We Do (Party) as she performed with a troupe of dancers.

Almost matching her outfit for brevity was fellow performer Jessie J, who wore a jewelled white minidress.

The former coach on BBC1's The Voice performed tracks such as Price Tag while showing her once-familiar black bob hairstyle is back following many months with a shorter blonde style after shaving her head for Comic Relief.

Other acts at the event included Enrique Iglesias, Australian pop act 5 Seconds Of Summer and Clean Bandit.

Brit Award-winning star Ellie Goulding performed earlier in the day, singing hits such as Burn and Goodness Gracious.

Many in the crowd had got into the party spirit by daubing their faces and arms with fluorescent body paint.

The event will also feature performances from Miley Cyrus and David Guetta.
